Detailed Description

Provides iterating through the document in terms of characters.

Only the editable characters are regarded.

This iterator represents the document, which is structured as a tree itself, as a linear stream of characters.

Constructor & Destructor Documentation

khtml::EditableCharacterIterator::EditableCharacterIterator ( )

inline

empty constructor.

Only use if you want to assign another iterator as no fields will be initialized.

Definition at line 999 of file khtml_caret_p.h.

khtml::EditableCharacterIterator::EditableCharacterIterator ( LinearDocument *  ld )

inline

constructs a new iterator from the given linear document.

Parameters

ld	linear representation of document.

Definition at line 1005 of file khtml_caret_p.h.

Member Function Documentation

CaretBox* khtml::EditableCharacterIterator::caretBox ( ) const

inline

returns the current caret box.

Will crash if beyond end.

Definition at line 1038 of file khtml_caret_p.h.

int khtml::EditableCharacterIterator::chr ( ) const

inline

returns the current character, or -1 if not on a text node, or beyond the end.

Definition at line 1018 of file khtml_caret_p.h.

void khtml::EditableCharacterIterator::initFirstChar ( )

protected

initializes the _char member by reading the character at the current offset, peeking ahead as necessary.

Definition at line 1744 of file khtml_caret.cpp.

InlineBox* khtml::EditableCharacterIterator::inlineBox ( ) const

inline

returns the current inline box.

May be 0 if the current element has none, or if the end has been reached. Therefore, do not use this to test for the end condition, use node() instead.

Definition at line 1045 of file khtml_caret_p.h.

bool khtml::EditableCharacterIterator::isEnd ( ) const

inline

returns true when the end of the document has been reached.

Definition at line 1027 of file khtml_caret_p.h.

long khtml::EditableCharacterIterator::offset ( ) const

inline

returns the current offset

Definition at line 1030 of file khtml_caret_p.h.

QChar khtml::EditableCharacterIterator::operator* ( ) const

inline

returns the current character as a unicode symbol, substituting a blank for a non-text node.

Definition at line 1023 of file khtml_caret_p.h.

EditableCharacterIterator & khtml::EditableCharacterIterator::operator++

(

)

returns whether the current line box represents the outside of its render object.

moves to the next editable character.

_peekNext

Definition at line 1767 of file khtml_caret.cpp.

EditableCharacterIterator & khtml::EditableCharacterIterator::operator--

(

)

moves to the previous editable character.

Definition at line 1869 of file khtml_caret.cpp.

void khtml::EditableCharacterIterator::peekNext ( )

inlineprotected

reads ahead the next node and updates the data structures accordingly

Definition at line 1066 of file khtml_caret_p.h.

void khtml::EditableCharacterIterator::peekPrev ( )

inlineprotected

reads ahead the previous node and updates the data structures accordingly

Definition at line 1081 of file khtml_caret_p.h.

RenderObject* khtml::EditableCharacterIterator::renderer ( ) const

inline

returns the current render object.

Definition at line 1033 of file khtml_caret_p.h.
